Answer:
b d
Step-by-step explanation:
The surface area would be 26.5487 m².
The surface area of a cylinder is equal to the area of the circles at both ends, added to the area of the rectangular portion in the middle. The rectangle in the middle has a width equal to the circumference of the circle and a length equal to the height of the cylinder.
The circumference of a circle is given by C = πd, and the area of the circles is given by A=πr².
Since the height is in meters, we will convert it to cm. 3.5 m = 350 cm.
The diameter is 190 cm, so the radius is 190/2 = 95 cm.
This gives us:
SA = 3.14(190)(350)+2(3.14)(95)²
= 208810 + 56677 = 265487 cm² = 26.5487 m²
Answer:
I think it's the 3rd one but tell me if I'm wrong
Answer:
Since L.H.S = R.H.S = 0, for both 
and 
, y₁ and y₂ both satisfy the equation y" - y = 0 and are thus solutions to the differential equation.
Step-by-step explanation:
To check whether the given functions are solutions the given differential equation, we differentiate the functions and then insert it into the given equation.
So y" - y = 0 and
Substituting these values of y and y" into the left hand side of the equation, we have
y" - y
Since L.H.S = R.H.S
So is a solution of the differential equation.
When
Substituting y and y" into the left hand side of the equation, we have
y" - y
Since L.H.S = R.H.S
So, is a solution of the differential equation.
The answer would be 35
5 x 7 = 35
